of two in both variants anyway.

1. Optionally add random "canaries" to the end of an allocation. This
requires increasing the internal size of the allocation slightly, which
probably results in a large effective increase with current power of two
sizing. Therefore, this option is only enabled via 'C'.
2. When writing junk (0xdf) to freed chunks (current default behavior),
check that the junk is still intact when finally freeing the delayed chunk
to catch some potential use after free. This should be pretty cheap so
there's no option to control it separately.

stubs for the executable from crtbegin.o into libc, which lets them be
excluded from static links that don't use them.
For this, drop the normal crt{begin,end}S.o from libc.so: the .init and .fini
sections for libc aren't called at the right times anyway, so it's good that
they're unused.  libc.so just needs __guard_local and the .note.openbsd.ident
section, so add them to stack_protector.c for now (this will be improved)

This provides consistent handling of SIGTHR between single- and multi-threaded
programs and is a step in the merge of all the libpthread overloads, providing
some ASM and Makefile bits that the other wrappers will need.

as OpenSSL is very liberal with what it allows.

cpu's specific hardware capabilities users of libcrypto might be interested
in, as an integer value. This deprecates the existing OPENSSL_ia32cap()
macro and the OPENSSL_ia32cap_loc() function (which returns the pointer so
that you can mess with stuff you shouldn't mess with).
Interpreting the value returned by OPENSSL_cpu_caps() is, of course,
machine-dependent.
Minor version bump for libcrypto.
